Inovatīva RF induktora barotāja datormodelēšana, izstrāde un eksperimenti

2018

Darbā tiek apskatītas dažādas iespējas ģenerēt augstas jaudas signālu ar atsevišķi regulējamu PWM (jaudas) koeficientu un frekvenci līdz 3 MHz. Tiek iztirzāti dažādi varianti praktiskā darba izpildei. Mūsdienās prasības germānija kristālu tīrībai aizvien aug un to audzēšana bezkontakta iekārtās var dot vajadzīgo rezultātu. LU ASI Atomfizikas un atmosfēras fizikas un fotoķīmijas laboratorijas efektīvās sadarbības projektā ar “Baltic Scientific Instruments Ltd” (lieto augstākās tīrības germānija kristālus) tika noskaidrots ka germānija kausēšanai vakuuma magnētiskajā levitācijā nepieciešams 30 kW un 0,5 - 3 MHz impulsa platumā regulējams (10 - 100% no jaudas) ģenerators, kas diemžēl komerciāl…
